Morphological changes in epididymal spermatozoa of Red Sokoto (Maradi) bucks

Abstract

Morphological changes in the caput, corpus and cauda epididymides were studied in this experiment. The objective was to study morphological changes in goat spermatozoa using the Red Sokoto goat. Progressive motile spermatozoa were tint observed in the caput epididymis (5-7%) and was highest at the cauda epididymis (60%). Progressive motility for the corpus epididymis ranged between 20-30%. Cytoplasmic droplets were lost as the spermatozoa moved up the epididymis. Proximal cytoplasmic droplet was significantly (P<0.05) lowest at the cauda epididymis. Other morphological changes did not follow a particular trend.
